Triethanolamine (TEA) is an organic compound commonly used as an emulsifier, surfactant, and pH adjuster in cosmetic and personal care products. It is a viscous, colorless liquid with a faint ammonia odor.

• Emulsifier: Triethanolamine helps to blend oil and water-based ingredients together in cosmetic formulations, allowing for a more even and stable product.
  
  
• Surfactant: TEA is a surfactant, which means it can help to cleanse the skin and hair by breaking down oils and dirt to be washed away with water.
  
  
• pH adjuster: TEA can adjust the pH of a product to make it more acidic or basic as needed. This can help to improve the stability of a formulation and enhance the effectiveness of other ingredients.

Overall, Triethanolamine is a versatile ingredient that can help to improve the texture, stability, and cleansing properties of cosmetic and personal care products. However, it should be used in moderation and in conjunction with other ingredients to avoid potential irritation or sensitivity.
